3. Cebe la bomba.

4. Vuelva a conectar la energía

eléctrica.

A medida que la bomba vuelve a llenar

el tanque, el control de volumen de

aire proporciona al tanque la

proporción correcta de aire y agua.

Luego la bomba se apagará en la

presión deseada. Si el tanque se vuelve

a inundar, revise el control de volumen

de aire y cámbielo si es necesario.

TANQUES PRE-CARGADOS

Si un tanque pre-cargado se inunda,

quizás la bolsa tenga una fuga o esté

rota.

1. Pruebe el tanque desenroscando la

válvula de aire. La válvula

descargará agua si la bolsa está

rota.

2. Si la bolsa, está rota, cambie el

tanque.

Cuando la bolsa de un tanque esté

rota, se deberá cambiar el tanque. No

se recomienda reparar la bolsa pues

puede causar problemas más adelante,

por ejemplo: continuas inundaciones,

desechos en las tuberías y descarga

obstruida en el tanque.

(Continuación)

2. Drene todas las tuberías hasta un

nivel por debajo de la línea de

congelamiento.

CÓMO DRENAR EL TANQUE

Se pueden drenar los tanques

convencionales al abrir una salida en el

punto más bajo del sistema. Retire un

tapón o el control de volumen de aire

para ventilar el tanque.

Los tanques pre-cargados fuerzan

prácticamente toda el agua fuera del

tanque cuando se libera la presión del

sistema. No se necesita drenaje.

TANQUES INUNDADOS

TANQUES CONVENCIONALES

Cuando un sistema de tanques tiene

una proporción inapropiada de aire y

agua, la bomba empezará a funcionar y

dejará de funcionar frecuente e

irregularmente.

1. Desconecte la energía eléctrica de la

bomba.

2. Abra la llave en la parte más baja

del sistema para liberar toda la

presión.

VERIFICACIÓN DE LA PRESIÓN DE

AIRE PARA TANQUES

PRE-CARGADOS

Es normal que haya pequeñas pérdidas

de aire en cualquier tanque. Para

prevenir cualquier falla y mantener

correctamente un tanque de agua pre-

cargado, verifique la presión

anualmente.

1. Desconecte la energía para

bombear.

2. Abra la llave más cercana al tanque

y deje drenar toda el agua del

tanque.

3. Mida la pre-carga del tanque en el

vástago de la válvula utilizando un

medidor de presión de

neumáticos.

4. Si es necesario, ajuste la pre-carga

con una bomba de aire; la presión

pre-cargada para la bomba JSU50 es

1,24-1,38 bar.

5. Cebe la bomba.

6. Vuelva a conectar la energía.

7. Cierre la llave.

WATER-LOGGED TANKS

CONVENTIONAL TANKS

When a tank system has an inadequate

ratio of air and water, the pump will

start and stop often and erratically.

1. Disconnect electrical power to

pump.

2. Open the lowest faucet in the sys-

tem to release all pressure.

3. Prime the pump.

4. Reconnect power.

As the pump refills the tank, the air vol-

ume control supplies the tank with the

correct air to water ratio. The pump

will then shut off at desired pressure. If

tank water-logs again, examine air vol-

ume control and replace if necessary.

PRE-CHARGED TANKS

If a pre-charged tank becomes water-

logged, the bladder is probably leaking

or broken.

1. Test the tank by depressing the air

valve. The valve will discharge water

if the bladder is broken.

2. If bladder is broken, replace tank.

Once a tank bladder is ruptured, the

tank should be replaced. Repairing the

bladder is not recommended, and may

cause further problems such as: repeat-

ed water-logging, debris in pipes and

clogged discharge in tank.

AIR PRESSURE CHECK FOR PRE-

CHARGED TANKS

Small amounts of air loss is normal in

any tank. To prevent failure and prop-

erly maintain a pre-charged water tank,

check the pressure on a yearly basis.

1. Disconnect power to pump.

2. Open a faucet nearest the tank and

allow all water to drain from the

tank.

3. Measure the tank pre-charge at the

valve stem using a tire gauge.

4. If necessary, adjust the pre-charge

with an air pump: Precharged pres-

sure for the JSU50 pump is

18-20 psi.

5. Prime the pump.

6. Reconnect power.

7. Close faucet.

4. After proper depth is reached,

install a well seal or pitless adapter

to support the pipe.

5. Slope the horizontal pipe upward

toward the pump to eliminate trap-

ping air.

DUG WELL, CISTERN, LAKE AND SPRING

INSTALLATION

1. Install a foot valve on the inlet pipe

and lower into the water.

Locate foot valve

at least 2 feet from

the bottom of the well so sand or sedi-

ment is not drawn into the system.

NOTE: When a lake is used for the

water supply, make sure the suction

pipe is deep enough to be submerged

at all times. Slope the pipe upward

toward the pump to eliminate trapping

air. The pipe must be removed during

winter months or protected against

freezing.

Protect the pipe

from damage by

swimmers and boaters.

Operation

PRIMING PUMP

Do not run pump

dry. Fill with water

before starting motor. Damage to pump

seals will result and void warranty.

After pump installation is complete, the

pump must be primed.

1. Remove the priming plug.

2. Fill pump and piping completely full

of water.

3. Replace the priming plug.

4. Open faucet to vent system.

5. Start the motor. Water will be

pumped within a few minutes. If

pump does not deliver water within

5 minutes, shut off motor and

return to step 1.

6. Let the system operate for several

minutes to flush out the pipes.

7. Close the faucet and allow pump to

build pressure in the tank. When

pressure reaches cut-out setting, the

motor will stop.

The system is now operating and will

cycle on demand.

NOTICE

WARNING

CAUTION

If the pump does not operate after

repeated attempts, check the follow-

ing:

1. Vertical distance of pump to water

must not exceed 25 feet.

2. Suction piping must be air tight.

3. Be sure valves are open if used in

discharge or suction piping.

Never run the

pump with a closed

or clogged discharge. The water inside

the pump could boil and damage the

pump.

The use of a foot valve is strongly rec-

ommended. This allows the suction line

to be filled during the priming process,

greatly decreasing priming times.

Maintenance

Disconnect power supply

and release all pressure from

system before attempting to

install, service, relocate, or perform any

maintenance. Lock the power discon-

nect in the open/off position. Tag the

power disconnect to prevent unexpect-

ed application of power. Serious injury

or death could result.

Maintain adequate ventilation for the

pump motor. The motor bearings are

permanently lubricated at the factory.

Additional lubrication is not required.

DRAINING PUMP

Drain openings are provided on all

models. To drain the pump:

1. Remove the drain fitting and prim-

ing plug.

2. Drain all piping to a point below

the frost line.

DRAINING TANK

Conventional tanks can be drained by

opening an outlet at the lowest point

in the system. Remove a plug or the air

volume control to vent the tank.

Pre-charged tanks force virtually all of

the water from the tank when the sys-

tem pressure is released. No draining is

necessary.
